Patented Aug. 1941 ms rss'rs msrnnsnn John 9.0mm, Missouh, Mont.- Application January as, 1940, sci-m Nana's -2cmmaicu21-co) This invention relates to a dispensing device designed primarily for use in supporting and dispensing pastes, and semi-liquid materials contained in tubes.

The primary object of the invention is to provide a support of this character having means to grip one end of the tube containing paste or semiliquid material, the means embodying a key to be rotated to compress the tube. forcing the material therefrom.

Another object of. the inventionis to provide a device of this character wherein the key will be supported in a true horizontal plane at all times thereby eliminating any possibility of the key twisting, as it is being rotated to eject the material from the tube.

A still further object of the invention is to provide a combined support and dispenser of this character, having a discharge opening, and a sliding closure operating adjacent to the opening, the closure being operated by contact of an article thereagainst, such as a tooth-brush or the like, so that the materiaidispensed, will be directed to the bristles of the tooth-brush or article on which the material is deposited.

With the foregoing and other objects in view, which will appear'as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of the invention herein described, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is an elevational view of a combined paste tube support and dispenser, constructed in accordance with the invention. 7

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a bottom plan view of the device.

Figure 4 is a transverse sectional view taken Figure 5 is a sectional view taken on line 5-5 of Figure 2. 4

Figure 6 is a sectional view through the carriage on which the key is supported.

Referring to the drawings in detail. the device comprises a box-like body portion, the front thereof being open. The body portion includes a rear wall 5, side walls 8, atop I, and a bottom 8. The bottom 8 isformed with a passageway 0 which is extended at an oblique angle with respect to the front and rear walls of the bottom l. portions of the passageway being vertical, one end of the passageway being threaded as at It. The bottom I is formed with inwardly disposed parallel flanges H. providing asupport for the sliding closure l2, the sliding closure being normally urged towards the front edge of the body portion, by means of the coiled spring l3. A stop indicatedat I4 i formed adjacent to the front edge of the body portion; and provides an. abutment against which the forward edge of the sliding closure I2 engages, restricting forward movement of the sliding closure.

As clearly shown'by Figure, 2 of the drawings,'

the sliding closure is formed with 9. depending extension l5 provided with a forwardly extended lip ii that provides a rest for an article, such as the tooth-brush indicated at A and shown in Fig- Y ure 1' of the drawings. a

Guide rods indicated at I! extend inwardly from the rear wall 5 of the body portion, and provide a support for the carriage I! on which the pressure rollers I! are mounted. The carriage includes horizontal arms 20 which are secured to the tubular bearings 2i that in turn are mounted on the guide rods II to move longitudinally thereof. Extending upwardly from the arms 20, is a frame indicated at 22 formed with a curved bearing surface 23 that provides a supp rt for the key indicated at 24. This key, extends through the body portion and is provided with en largements 25 that are disposed in the guideways 26 formed within the body portion and disposed adjacent to the side edges thereof. The guideways and enlargements are of such construction that the key will be held in a true horizontal position at all times, eliminating any possibility of the key twisting, as it is being moved through the housing or body portion. As shown, the key is formed with a longitudinal slot 21 into which the crimped end of a paste tube is positioned, so

that when the key is rotated, the tube will be wound on the key, feeding the carriage longitudinally of the housing or body portion. The pressure rollers I! operate in advance of the key, and are designed to exert pressure on the tube supported within the body portion, to squeeze the contents of the tube therefrom.

On one endof the key 24, is a finger piece 28 thatisdisposedexteriorlyofthebodyportion,

sothatitmaybegrippedbytheoperatortorotate the key and'accomplish the purpose of the invention.

In order that the key may slide longitudinally of the body portion, elongated openings 2! are formed in the partitioning members 8| .and one sidewallofthebodyportiomeothatthekey cessive quantity of material being dispensed.

may move longitudinally of the body portion when it is being rotated to force material therefrom.

In the use of the device, it will of course be understood that asuitab1e bracket or support will be provided so that the body portion may be secured to a supporting surface. The tube to be used with the device is now positioned by threading the nozzle thereof into the threaded opening it of the passageway 8. The crimped end of the tube is now positioned within the slot of the key, and the rollers I! forced over the tube.

By rotating the key, it is obvious that pressure will be directed to the tube, forcing material therefrom to fill the passageway 9. When an article such as a tooth-brush is positioned When pressure on the tooth-brush is released,

the sliding closure l2 will be returned to its closing position by the action of the coiled spring ii. The ribbon of paste or material passing from the passageway 9, will be cut oil. to prevent an ex- What is claimed is: v

l. A paste tube support, comprising a body portion, vertical guide rods secured within the body portion and supported on the rear wall thereof, a vertically movable carriage including supporting arms, vertical tubular bearings on the inner ends Cit I the last mentioned horizontal bars for directing a .of said arms, said bearings having openings through which the guide rods extend, holding the carriage in alignment with the walls of the body portion, a key having a slot in which one end of a paste tube is held, the ends of the key being rotatably supported in the carriage, and pressure rollers mounted on the carriage and between which said tube is pressed when the key is rotated on the carriage, whereby paste is forced from the ube.

2. A paste tube support comprising a body portion, vertical guide rods secured to the rear wall of the body portion and disposed in parallel spaced relation with respect to each other, said rods being also spaced from the rear wall of the body portion, a carriage including end members, supporting rods forming a part of the end members, tubular bearings on the inner ends of the supporting rods and adapted'to receive the first mentioned rods, slidably mounting the carriage on the vertical rods, horizontal rods connecting the end members, rollers on the last mentioned rods, said rollers operating in parallel relation with respect to each other, said end members of the carriage having curved upper surfaces, 9. key resting in the curved upper surfaces of the end members, said key having a slot in which one end of a paste tube is held, and'said key adapted to I wind the paste tube on the key, forcing materialfrom the tube, and pressure rollers mounted on pressure to the tube in advance of the key.
